The Belomorian Province of the Fennoscandian Shield exposes numerous Precambrian eclogites, which makes it significant for study early tectonic processes. age these eclogites has been discussed more than 15 years and regarded as either Archean or Paleoproterozoic. In Kuru-Vaara quarry within northern Province, eclogitic assemblage is preserved in concordant mafic boudins felsic gneisses a parti...

In Western Himalayan Syntaxis, the India-Asia continental collision occurred at ca. 50 Ma, while its uplift history and exhumation mechanism are still in dispute despite decades of studies. A new type eclogite was found Naran, located 30 km southwest Upper Kaghan Valley. Phase equilibrium calculations thermobarometer performed on Naran documented peak-P metamorphic condition 720–780°C 2.4–2.8 G...

The presence of mélange at the subduction interface influences numerous geochemical and geophysical processes. However, relationship between timescales development, deformation, resultant mass transport is poorly understood. Here, we use Sm-Nd garnet geochronology to elucidate timing peak metamorphism for five amphibolite tectonic blocks from amphibolite-facies zone Catalina Schist (Santa Islan...

The present study indicate that the copper mineralization in the area is of the nature of scattered sporadic occurrences of narrow lenticular and impersistent stringers and veins of copper-ore in vein-quartz and pegmatite traversing the amphibolite and garnetiferous mica schist country rock. The old workings for copper ore at Garimanipenta, which had a checkered history since early times, are b...
